Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
nhung cong » dung cong, thong cong, hang cong
doi chieu » doc hieu, doi chi, ho chieu
truong va » truong dai, truong cao, truong dao
trung ha » trung hoc, trung tam, trung cap
dan than » dan chan, van than, dan toan
ban than » ban thanh, van thanh, ban hang

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu xanh - thanh ((truong va) OR (trung ha)) nhung cong ((dan than) OR (ban than)) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu xanh - thanh ((truong va) or (trung ha)) nhung cong ((dan than) OR (ban than)) cao~".
• Adding a wildcard symbol may retrieve word variants: doi chieu xanh - thanh ((truong va) or (trung ha)) nhung cong ((dan than) OR (ban than)) cao*.
